Ultrasound is a diagnostic imaging technique that uses ultrasound waves (high-frequency sound waves) to build and recreate images of the body's internal structures. Ultrasound is a method of diagnosing and treating diseases that is commonly used in medicine.

Intravenous contrast-enhanced ultrasound is indicated in cases where it is necessary to evaluate the dynamics of tumors, especially liver tumors. It supports percutaneous interventions under ultrasound guidance and evaluates the effectiveness after treatment (after radiofrequency ablation, alcohol injection, hepatic embolization, etc.)
